^m Device for parking vehicles or storing containers "

The invention relates to a device for parking vehicles or storage of containers or the like. Goods.

Because of the increasing scarcity of free usable space, it has long been known to put vehicles in multi-storey car parks in several b to be placed on top of each other. However, there is a considerable Amount of valuable floor space lost as a result of the fact that Rauttverxehrende Access and exit routes to connect the individual Parking levels below each other as well as with an entrance and an exit for the vehicles are required. This loss at Floor space can also be increased by using transport Do not avoid trains completely, because then the elevator shaft • needs a significant amount of seams. In addition, #edem Fall on the individual parking lanes of considerable width be kept free so that the vehicles can get to their parking spaces

If the serious part of a small storage capacity related to the base area is raised, there is also a risk of mutual damage to the incoming and outgoing vehicles in multi-storey car parks.

An embodiment of the invention which is particularly advantageous from a structural point of view is obtained in that the bath disks consist of a number of spokes and an outer bath rim which are connected to one another by the bearing axles for the casing. Such a design of the device saves material and is light, which also results in cost savings in the foundations for the bearing of the axle of the wheel-bearing gate.In addition, the structurally light design of the device results in considerable savings in drive energy for the rotary movement of the carrier · This embodiment can be further developed in an expedient manner by the fact that at least one further concentric wheel rim is provided between the outer bath rim and the itorisontal axis for the wheel-shaped carrier, and the number of spokes connecting adjacent wheel rims is reduced from the outer bath crane to the axis. As a result, the spacing of the spokes on the axially close cranks can be kept just as large as the spacing of the spokes on the farther outward baths, so that the free openings between the bsinachljarten storages can be kept approximately the same size over the entire radial extension of the wheel-farted door. 3amit is radially outward in both radial as ittn ^ v ^ v} areas the carrier is always a OTWA equally large Durchgaag swischen ä & a Spoichen through to the swischen the two bath | disc-mounted gahäua «n guaranteed · |

Xn adaptation to the conditions of the location for the device it can be useful to use the wheel-shaped carrier in part to be stored in a fixed pit. This enables world-wide adaptation to the architectural structure of the environment. For protection against weather influences as well as aesthetic and architectural reasons it turns out to be in many Cases further than appropriate for those who are superior to the level A structural casing is to be provided for part of the bicycle carrier.

According to another feature of the invention, it can be expedient to arrange the wheel-shaped carrier in such a way that it protrudes above the level by at least the simple housing height. In this way, a simple loading and unloading of the device from the level is possible, so that at least one housing can then be brought up to the level with its base. In contrast to this, however, another embodiment also proves to be particularly advantageous, in which the axis of the carrier is arranged above the level by approximately the simple housing height. If, with such an arrangement, the bottom of a housing is on Niva & uhSfae, then the radius of the face disks drawn from the axis of rotation of the wheel-shaped support above the end of the housing runs parallel to the plane of the level, so that several

Similar gates 17 can also be provided in the part of the building 16 broken away in the drawing in order to provide access to the illustrated enclosures 14 and 14 for vehicles entering and leaving or loading and unloading the goods.

To the in Flg. 2 shown elevation in dter Badialeben "de" radfuraigen carrier 1 according to FIG. 1 as well as in Flg. 3 The associated axial section shows "that in the case of the embodiment the upper horizontal axes 7b" - stiaeatoa suspension points for the housings 9 on two circles 18 and 18 * which are consistent with the wool 5, "with the radially outer one lying circle 18 has a slightly smaller diameter than the outer crane 3 ', and the further inner circle 18 * has a radial distance r from the outer circle 18, which is greater than the largest in the Badialebane dimension of the Gahause 9 _P, i.e. the diagonals d dar housing 9, so that the outer circle 18 augeordaaton housing 9 does not kiss those of the inner Kroisos 18 ° against the threat of the carrier 1 in contact.

To this end, the distance between adjacent spokes 4 should be slightly larger than the vertical height h of the housing 14 * when the spoke 4 'is in a horizontal position with the radially most inner wall 19 of the housing 14 *.

As can be seen in the schematic representation according to FIG. 4, in the event that the horizontal position of the spoke 4 * carrying the housing 14 is provided as the loading and unloading position, the wheeled carrier 1 is in a pit in this way 20 housed that its axis 5 la one »; Height h ^{1 is} above the level 21, which is approximately the same as the height h of the housing 14.
